This example shows how to visualize frequency input signals with the Spectrum Analyzer block.

To visualize frequency-domain input signals using a Spectrum Analyzer block, in the Estimation tab of the Spectrum Analyzer toolstrip, set Input Domain to Frequency. In the Spectrum tab, clear the Two-Sided Spectrum parameter.

Run the model. You can see two peaks. To measure the peaks, enable Peak Finder in the Measurements tab.
